Emulsifiers for microcapsules, the use of this an emulsifying agent are in microcapsules and a method for the preparation of microcapsules, application of pressure sensitive by write paper.

摘要

Disclosed in this invention are an emulsifier for producing microcapsules, containing as active principle a water-soluble polymer the emulsifier being composed of benzyl (meth)acrylate and/or diisobutylene, styrene and maleic anhydride, microcapsules using the emulsifier, a process for producing the microcapsules, and a non-carbon pressure-sensitive copying paper using the microcapsules.
